Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1302F be used as a direct replacement for RK73H1HTTC1302F?

A: Yes. RK73H1HTTCM1302F is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. All electrical parameters (13 kOhms, ±1%, 0.05W), mechanical specifications (0201 package), and compliance ratings (AEC-Q200, ROHS3, MSL 1) are identical.

Q: What is the difference between RK73H1HTTC1302F and RK73H1HTTCM1302F?

A: The primary difference is product status. RK73H1HTTC1302F is "Not For New Designs," while RK73H1HTTCM1302F is "Active." Both parts share identical electrical and mechanical specifications. The "M" designation in the part number indicates the active production variant.

Q: Can YAGEO AC0201FR-0713KL replace KOA RK73H1HTTC1302F in automotive applications?

A: Yes. AC0201FR-0713KL meets all specified parameters including AEC-Q200 automotive rating, identical resistance (13 kOhms ±1%), power rating (0.05W), package format (0201), temperature range (-55°C ~ 155°C), and RoHS compliance. It is suitable for direct substitution in automotive circuits.

Q: Are there packaging differences between the substitute parts?

A: RK73H1HTTC1302F and AC0201FR-0713KL are both supplied in Tape & Reel (TR) format. RK73H1HTTCM1302F packaging format is not specified in available documentation. Confirm packaging requirements with the supplier before procurement.

Q: What is the significance of the "Not For New Designs" status?

A: This status indicates that KOA Speer Electronics has discontinued active development and new design integration of RK73H1HTTC1302F. Existing production systems may continue using available inventory, but new circuit designs should utilize the active substitute RK73H1HTTCM1302F or AC0201FR-0713KL.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts listed carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are temperature coefficient specifications identical across all parts?

A: Yes. All parts specify ±200ppm/°C temperature coefficient and operate across the -55°C ~ 155°C temperature range.
